High rise aerial appliances for fire service use - Turntable ladders with sequential movements - Safety and performance requirements and test methods

1.1   This European Standard specifies the safety and performance requirements and test methods applicable to turntable ladders with sequential movements of classes 18, 24 and 30, as defined in 3.13, under the control of firefighters and intended for fire fighting and rescuing people.
NOTE   This European Standard is intended to be used in conjunction with EN 1846-1, EN 1846-2 and EN 1846-3.
Turntable ladder vehicles comprise a chassis, bodywork and a powered extending structure unit in the form of a ladder with or without a cage.
Turntable ladder vehicles covered by this European Standard have a self-propelled chassis, the motor of which supplies the power required for the operation of the ladder. They do not permit operational movements to be made simultaneously.
1.2   This European Standard deals with the technical requirements to minimise the hazards listed in Clause 4 which can arise during the commissioning, the operational use and the routine checking and maintenance of turntable ladders when carried out in accordance with the specifications given by the manufacturer or the manufacturer authorised representative.
It also deals with performance requirements.
1.3   This European Standard deals with the use of turntable ladder vehicles within a temperature range from - 15 °C to + 35 °C and with a wind velocity on the ladder set <= 12,5 m/s. Additional measures can be necessary for use outside this range (to be negotiated between the manufacturer and the user).
NOTE   Special designs for use under special climatic conditions should be by arrangement between the manufacturer and the purchaser.
1.4   This European Standard is not dealing with the hazards of the standard automotive chassis or due to use as a road vehicle.
1.5   This European Standard is not applicable to turntable ladders vehicles with sequential movements which are manufactured before the date of publication of this European Standard by CEN.

Hubrettungsfahrzeuge für die Feuerwehr - Drehleitern mit aufeinander folgenden (sequenziellen) Bewegungen (Halbautomatik-Drehleitern) - Sicherheits- und Leistungsanforderungen sowie Prüfverfahren

1.1 Diese Europäische Norm legt die Sicherheits- und Leistungsanforderungen sowie die Prüfverfahren für
Drehleitern mit aufeinander folgenden (sequenziellen) Bewegungen (Halbautomatik-Drehleitern) fest,
eingeteilt in die Klassen 18, 24 oder 30 (siehe 3.13), die von Feuerwehrpersonal bedient werden und für die
Rettung von Menschen sowie die Brandbekämpfung vorgesehen sind.
ANMERKUNG Diese Europäische Norm ist für die Anwendung in Zusammenhang mit EN 1846-1, EN 1846-2 und
EN 1846-3 vorgesehen.
Drehleitern bestehen aus einem Fahrgestell, einem Aufbau und einem kraftbetrieben Ausleger in Form einer
Leiter mit oder ohne Korb.
Die in dieser Europäischen Norm behandelten Drehleitern verfügen über ein selbstfahrendes Fahrgestell,
dessen Motor die für den gesamten Betrieb der Drehleiter notwendige Energie liefert. Die Einsatzbewegungen
können nicht gleichzeitig ausgeführt werden (Halbautomatik-Drehleiter).
1.2 Diese Europäische Norm behandelt die technischen Anforderungen zur Minimierung der in Abschnitt 4
aufgeführten Gefährdungen, die während Inbetriebnahme, Bedienung, regelmäßigen Überprüfungen und
Wartung von Drehleitern auftreten können, wenn diese Tätigkeiten entsprechend den Festlegungen des
Herstellers bzw. dessen bevollmächtigten Vertreters durchgeführt werden.
Leistungsanforderungen werden ebenfalls behandelt.
1.3 Diese Europäische Norm behandelt den Gebrauch von Drehleitern innerhalb eines Temperaturbereiches
von –15 °C bis 35 °C und bei einer an der Leiter wirkenden Windgeschwindigkeit von ≤ 12,5 m/s.
Für den Gebrauch außerhalb dieses Bereiches können zusätzliche Maßnahmen erforderlich sein (zu
vereinbaren zwischen Hersteller und Kunden).
ANMERKUNG Spezielle Bauarten für den Gebrauch bei besonderen klimatischen Bedingungen sollten zwischen
Hersteller und Kunde vereinbart werden.
1.4 Diese Europäische Norm gilt nicht für die Gefährdungen des Standard-Fahrzeuggestells oder durch
den Gebrauch als Straßenfahrzeug.

Les véhicules à échelle pivotante comprennent un châssis, une carrosserie et une structure extensible motorisée,
sous la forme d'une échelle avec ou sans panier.
Les véhicules à échelle pivotante couverts par la présente Norme européenne ont un châssis automoteur, dont le
moteur assure la puissance requise pour faire fonctionner l'échelle. Ils ne permettent pas de faire simultanément des
mouvements opérationnels.
1.2 La présente Norme européenne traite des prescriptions techniques destinées à minimiser les phénomènes
dangereux énumérés à l'Article 4, pouvant survenir pendant la mise en service, le fonctionnement, la vérification et la
maintenance de routine des échelles pivotantes, effectués conformément aux spécifications données par le fabricant
ou son représentant autorisé.
Il traite également des prescriptions de performances.
1.3 La présente Norme européenne traite de l'utilisation des véhicules à échelle pivotante dans une plage de
température de – 15 °C à + 35 °C et avec une vitesse de vent sur la structure extensible ≤ 12,5 m/s. Des dispositions
supplémentaires peuvent être nécessaires pour un usage en dehors de cette plage (à négocier entre le fabricant
et l'utilisateur).
NOTE Il convient de définir les conceptions particulières relatives à un usage dans des conditions climatiques spéciales
entre le fabricant et l'acheteur.
